It’s been a perfectly pleasant summer in Indiana, hasn’t it?
Right, so long as you’ve never stepped a foot outside your air-conditioned home and you live far enough away from a cornfield.
For the rest of us, summer has been a grueling, hot and sweaty mess. The latest heat dome isn’t helping.
If your heart is already set on autumn leaves and Pumpkin Spice Lattes, the Old Farmer’s Almanac has issued its seasonal fall weather forecast for the Midwest. Their prediction paints a cool and crisp looking autumn.
Climatologists at the National Weather Service, however, might disagree.
Here’s what forecast models are predicting for Indiana when summer ends and fall begins.

When is the first day of fall?

Old Farmer’s Almanac: Fall 2025 forecast for Indiana
The Old Farmer’s Almanac, not to be confused with the Farmer’s Almanac, is predicting a “cool and dry” fall for Indiana and the larger region
Both the Ohio Valley and upper Midwest are predicted to have cooler than normal temperatures in September and October, writes the Old Farmer’s Almanac, by as much two degrees.
Farmer’s Almanac issues Autumn Outlook for 2025
The 2025 autumn outlook by the Farmer’s Almanac is calling for a “flirty, flurry, fall” this year.
“Fall 2025 is shaping up to be a season of contrasts across the United States,” writes the almanac. “From early chills in the North to lingering warmth in the South, and from stormy skies to tranquil stretches, this fall will keep us on our toes.”
The Midwest can expect clear skies in September with a “tug-of-war between fair weather and storm systems,” according to the almanac. Severe thunderstorms and the potential for a tornado “will loom over the central states, particularly the Ohio Valley and the Plains.”
October and November are predicted to bring traditionally cool weather to large swaths of the country, with the Great Lakes regions seeing a chance for early snow.
Whether either almanac gets it right this year remains to be seen.
How accurate are the Farmer’s Almanac and Old Farmer’s Almanac?
Despite assertions the almanacs are 80-85% accurate, studies have shown their long-range predictions are sometimes little better than a coin flip. One study cited by Popular Mechanics reported the Farmer’s Almanac was right about 52% of the time.

Indiana has a 33-50% chance of seeing warmer than normal temperatures from September through November, according to NOAA.
